Anyone care to review their copy of Elliott and Cobb for the page (upper left of left page) picturing the higher grade with two different serial numbers stamped on barrels? I'd appreciate a summary of the relative discussion.

The following photos demonstrate the different, but sequential, serial numbers on this G. I consider the gun to be originally stamped 45657. This number matches the trigger guard in both places and the forend.

Based on my brief review of the page mentioned above ), I considered 45656 to be a later stamp. The stampings are definitely from different tools.

The possible evidence of factory work is the serial 45656 stamped on the extractor (you should be able click on the picture to zoom). Interestingly, the tools for this stamping looks to be the same as those used for the 45657 on the barrel.

To an even lesser degree of certainty, under the 3/4" LAC buttplate are two sets of screw holes that may indicate a factory change of plate. The original set of holes being plugged to some extent.
